1. 复现问题

今天准备克隆Redis桌面(GUI)管理客户端,故按照官方文档给出的指令运行时,如下图所示:

但在执行指令npm install --platform=win32却报出如下图错误:

PS D:\Software\RedisDesktopManager\AnotherRedisDesktopManager> npm install --platform=win32
npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead.

npm ERR! Cannot read properties of null (reading 'pickAlgorithm')
npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\zxy\AppData\Local\npm-cache\_logs\2022-11-04T07_24_57_963Z-debug-0.log

注意看上述错误的倒数第3行,即Cannot read properties of null (reading 'pickAlgorithm')

2. 分析问题

Cannot read properties of null (reading 'pickAlgorithm')翻译成中文就是无法读取 null 的属性(读取 'pickAlgorithm')

但是,我在运行指令npm install --platform=win32时,并没有涉及pickAlgorithm字段呀,于是,通过查找资料可得如下解决方案:

  1. 方案1

重新安装node解决,这并没有解决我的问题,舍弃。

  1. 方案2

删了node models重新下。

或者直接下载CNPM(淘宝镜像)进行安装CNPM安装办法:

npm install -g cnpm -registry=https://registry.npm.taobao.org

查看cnpm是否真安装成功:

cnpm -v

这种方式也没有解决我的问题。

于是,使用如下第3种方案解决了我的问题。

3. 解决问题

  1. 在终端输入指令npm cache clear --force,如下所示:
PS D:\Software\RedisDesktopManager\AnotherRedisDesktopManager> npm cache clear --force
npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead.
npm WARN using --force Recommended protections disabled.
  1. 再次执行指令npm install --platform=win32,即可完成安装,如下所示:
PS D:\Software\RedisDesktopManager\AnotherRedisDesktopManager> npm install --platform=win32
npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead.

  1. 输入npm start启动程序,如下图所示:

此时,报出另外一个错误,即 Cannot find module 'D:\Software\RedisDesktopManager\AnotherRedisDesktopManager\node_modules\fs.realpath\index.js'. Please verify that the package.json has a valid "main" entry

即在当前目录下找不到index.js文件,于是,我们去当前目录下区创建该文件即可:

创建index.js文件后,再次执行npm start指令,即可启动程序了,如下所示:
